<p>A system and method for detecting ingress on shared media is presented. In oneembodiment, among others, an input signal is selectively attenuated at eachsource site using a pseudo-random pattern, thereby amplitude modulating atlow level the signal in a pseudo-random manner. Each encoded signal from eachof the source sites is combined on shared media connected to a headend. The headendreceives a composite signal comprising all of the individual source site signalsand extracts the source site information using the pseudo-random pattern, therebydetermining which of the source sites is the source of ingress.</p> |
